1. HoverNotes
HoverNotes turns video tutorials into interactive learning tools by using Google Gemini 2.0 AI to extract and neatly organize technical content. It's packed with features that make note-taking during tutorials a breeze.
This extension doesn’t just rely on transcripts. It analyzes both audio and visuals in real time, creating detailed notes with syntax highlighting. As the HoverNotes FAQ states:
"Unlike tools that only read transcripts, our AI (powered by Gemini 2.0) watches and understands video content directly. This means we can capture visual elements, diagrams, and interactions that don't appear in transcripts, making your notes more comprehensive."
A split-view mode lets you watch the video while taking notes side by side, avoiding the hassle of switching windows. It also auto-timestamps notes and screenshots, a feature that sets HoverNotes apart.
Your notes are stored locally in Markdown format and can be synced with Obsidian. The tool works seamlessly with platforms like YouTube, Udemy, Coursera, and LinkedIn Learning .
| Feature | Free Plan | Standard Pack ($8) | Semester Pack ($20) |
|---|---|---|---|
| Basic Features | ✓ | ✓ | ✓ |
| Obsidian Integration | ✓ | ✓ | ✓ |
| AI Processing Minutes | 30 | 500 | 1,250 |
| Local Storage | ✓ | ✓ | ✓ |
Users have shared glowing feedback. Developer Abdallah Mtavya highlighted:
"The real-time AI-powered notes, complete with syntax-highlighted code snippets and screenshots, have saved me so much time - no more rewinding videos to catch details!"
HoverNotes supports note-taking in over 15 languages, allowing users to create notes in their preferred language even if the tutorial is in a different one.
With over 10,000 active users and a flawless 5.0/5 rating on the Chrome Web Store, HoverNotes is making video-based learning much more efficient. By eliminating manual note-taking and constant rewinding, it helps developers stay focused during tutorials.
2. CodeSnap
CodeSnap is all about making it easy to grab and organize code snippets directly in Visual Studio Code. With over 2.79 million installs, it’s a go-to tool for developers focused on technical learning and documentation.
Since it works right inside VS Code, there's no need to juggle multiple tools. You can activate it through the command palette, a right-click menu, or custom shortcuts, keeping things simple and fast.
Customizable Snapshot Settings
CodeSnap lets you tweak how your code snapshots look, giving you control over the visuals:
| Setting | Function | Default |
|---|---|---|
| Background Color | Adjusts the container's background | White |
| Box Shadow | Adds depth to the snippet | Enabled |
| Line Numbers | Displays or hides line references | Optional |
| Window Controls | Adds OS X-style window buttons | Optional |
| Rounded Corners | Changes the appearance of corners | Optional |
You can save snapshots or copy them using the codesnap.shutterAction setting. On Linux, clipboard functionality requires installing xclip or wl-clipboard, depending on your display server. There's also the realLineNumbers option, which keeps the original line numbers intact - perfect for tutorials or documentation.
Why CodeSnap Stands Out
CodeSnap works seamlessly across various coding environments, making it a great fit for developers using different platforms and programming languages. You can even bind the codesnap.start command to a keyboard shortcut for quicker access.
What sets CodeSnap apart is its direct integration into the IDE. Unlike web-based tools, this extension keeps everything in one place, reducing distractions and helping you stay focused during coding sessions. While HoverNotes is great for detailed note-taking, CodeSnap specializes in managing code snippets efficiently within your workspace.

3. TutorialHelper
TutorialHelper makes video learning more effective by offering advanced playback options and a cloud-based system for organizing notes. It helps developers get the most out of video tutorials while keeping their resources neatly structured.
Smart Playback Controls
With TutorialHelper, video playback becomes much more flexible than YouTube's standard options. Instead of being limited to speed adjustments between 0.5× and 2×, TutorialHelper lets you fine-tune playback from 0.25× to 5× for a tailored viewing experience.
Organized Note-Taking for Developers
TutorialHelper’s note-taking system is specifically designed to fit the needs of developers, offering a variety of features:
| Feature | Function | Benefit |
